I am trying to implement the sdk of verifinger 10 and I was stuck with the following problem, I could not initialize the reader, ie following the flow of the AbisSampleCS demo I have seen that with the following method:

Beforehand thank you very much for responding, I tell you that detail I could solve it and today I encounter another problem.

The reader that I need to use is a Digital Persona U.are.U 4500, which is not recognized by the sdk, I am currently working with the sdk 10 of verifinger, I also have a UPEK TCS2C # 1 reader with which I do my tests , But as I commented, the one I need to be able to use is the digital UareU 4500 person

I would like to know if they could support me for the SDK to recognize this reader.

I tell you, in fact the device is configured in Windows10, the details of the driver are as follows:Driver Provider: DigitalPersona, Inc,Date of the controller: 08/10/2008Driver Version: 4.0.0.128

My development environment is installed on Windows 10 Pro x64, do not know if that affects something?

As I said, using the example that comes in the sdk (AbisSampleCS) does not recognize the device, I have 2 different readers (U.are.U FingerPrint Reader 4500 and UPEK TCS2C # 1) with upek reader the AbisSampleCS demo works perfect but With the reader U.are.U 4500 simply does not recognize it, I was also testing the demo DevicesSampleCS to be able to verify if I lacked any component or reference but also in this project does not work the reader U.are.U 4500, my request for support is But if any further processing is necessary to make the U.are.U reader recognized? Since the reader works perfectly, only that I can not register it with the sdk 10.

I hope I can help the sdk recognize the reader U.are.U

Hello lchavez,

You have to install drivers from “Scanners and cameras drivers” pack from link: http://www.neurotechnology.com/download ... _sdk_trial. I have installed from this pack and they are different than you are using, mine: 02/24/20104.0.0.143Uninstall driver, then install it from this pack and test again with DevicesSampleCS.

I need more of your valuable support, I tell you, in the example AbisSampleCS there is a control called fingerSelector, that control is the one that graphically asks the fingerprints in a certain order, I wonder how I can transfer that control to a project outside the AbisSampleCS example , Since I was analyzing it and according to I only occupy 2 classes: FingerSelector: Control and FingerSelector.Designer.cs, I have already created the same classes in my new project, but when they start loading the components it sends the error: Can be null Parameter name: bytes "Could you please tell me how to create this control in a new project? That is, what components it uses to be fully functional.

Hello lchavez,

Sample was written without intention that somebody will take piece out and try to use it on other project, so unfortunately I don't have instructions how to do that. You will have to investigate how it is used within the sample project and then adapt it into your own.

Oh I see, I regret not being able to count on your support for this task, however your support has been very useful in the development of this project, thank you very much, in case I get more doubts I will contact you again.

I do not know if they could guide me, since all the components are initialized correctly, the fingerprint is displayed but it sends the error.

I remain attentive to your comments.

Best regards

Hello lchavez,

There already been questions about this error in forum, if you have used search, you would have already got the answer:It requires "SDK\Bin\Data\FingersDetectSegmentsClassifier.ndf" file, store it to your application's working directory.
